Gullfoss is a waterfall on the Hvítá River in Haukadalur in southern Iceland. Its average water flow is around 109 m3/s, in summer around 130 m3/s. The largest discharge measured so far was 2000 m3/s. The waterfall consists of two levels, the first of which is 11 m high and the second 21 m high. These two cascades are approximately at right angles to each other. From the second stage, the water rushes into a gorge, which from the waterfall to the widening to the valley is 2.5 km long and reaches a depth of 70 meters. The waters of the Hvítá and last but not least the occasional glacier runs have carved this gorge by an average of 25 cm a year since the Ice Age 10,000 years ago.
Two glacier runs in the 20th century are known, 1930 and 1948. During these, the gorge was completely filled with water, so that the lower waterfall level temporarily disappeared underneath.[1]
